    摘要： An image forming apparatus including an image bearing member to bear a latent electrostatic image, a charging member to charge a surface of the image bearing member, an irradiation member to irradiate the image bearing member to write the latent electrostatic image, a development member to develop the latent electrostatic image with a toner to form a visualized image, a transfer device to transfer the visualized image directly or via an intermediate transfer body to a recording medium, a fixing device to fix the transferred image transferred on the recording medium and a cleaning device to remove residual toner remaining on the image bearing member. In the image forming apparatus, the cleaning device includes an elastic member having a blade forming a front end which is in contact with the image bearing member at a pressure of from 2 to 6 MPa and the toner is granulated in an aqueous phase and contains a laminar inorganic mineral having ions between layers at least part of which is modified by an organic ion and an average of a form factor SF-1 of the toner is from 130 to 160.
